Today, we're at the cold storage facility in Dandenong, which is just on the outskirts of Melbourne. The job here today is a 210 kilowatt system 530 to 400 watt panels. They're the high efficiency premium panels on the market, paired that up with seven inverters. It all ties into the main switchboard and produces power, enough to supply this entire building.
The solar for cold storage facilities is very relevant just because it's a very stable energy load. They have the fridges on 24 hours a day, seven days a week and the solar energy can cover about 40% of their load. So on this job here, because we've got a North South aspect to the roof, the rows on this North side they're a little bit closer together. All the panels are tilted up at 15 degrees. So, on the other side with the roof slanting back towards the South a little bit, we've just placed the rows a bit further. Just so that the row in front doesn't shadow the row behind it. For customers like this, it is about saving money, the solar is really an easy decision to make. It saves a substantial amount of money, reduces their energy costs and gives them energy security for the next 25 years.
So, the return on investment on this particular site is 4.6 years until the system pays for itself. We set that up conservatively with the 3% increase on their rate of power over the next 25 years. So, the site here at this cold storage facility, has got a 210 kilowatt system. It's going to save them $80,000 in the first year. At the 25 year mark, the system will still be producing and they'll have a total saving of $1.6 million. We get to these figures because we analyze the interval data for the site. We designed the system to suit their actual requirements that they need. Through that data, we get it every 15 minutes, it's very accurate, and we base that on weather data from the Bureau of Meteorology that goes back 20 years.
How will a commercial solar power system help a cold storage facility save $1.6 million dollars?
